摘要: The invention relates to novel acetoacetylated diamines and polyamines and to a method for the production thereof. The acetoacetylated diamines and polyamines are compounds of formula (I), wherein R?1 and R2¿, independent of one another, represent hydrogen or C¿1-6? alkyl, and A represents C3-8 cycloalkanediyl or a group of formula (II): -(CR?3R4)¿p-[NR-(CR5R6)q]r .

摘要: The invention relates to a method for producing α-dicarbonyl compounds of formula (I), wherein R?1 and R2¿, independently of each other, mean C¿1-6?-alkyl. Said method is characterised in that an α,ß-unsaturated ketone of formula (II), wherein R?1 and R2¿ have the meaning above and R?3 and R4¿, independently of each other, mean hydrogen, C¿1-6?-alkyl or di-C1-6-alkylamino, is reacted with ozone and the resulting ozonide is treated reductively.

摘要: Novel acetoacetylated aromatic amine compounds are claimed. - Novel acetoacetylated aromatic amine compounds (I) are of formula (1). - R1, R2 = OH, 1-6C alkyl, 1-6C alkoxy, halogen, phenyl or phenoxy; - R3 = H or 1-6C alkyl; - m = 0-4; - n = 0-5. - Independent claims are included for: - (i) a process for the production of the compounds (I) (R3=1-6C alkyl) by reaction of diketene with an N-phenyl-p-phenylenediamine of formula (2) in the presence of 3-40 % acetic acid at 20-100 (60-70) degreesC; - (ii) new unsaturated amino-ketone compounds (II) of formula (3) prepared by reaction of the amine compound (I) with ammonia; and - (iii) new amino-ketone compounds (III) of formula (4) prepared by catalytic hydrogenation of (II).
